Santa Ana (Ecuador) Court Case: Rights of the Portoviejo River

Summary

On 10 February, 2026, a judge in the Santa Ana Multicompetent Judicial Unit issued a ruling that declared the Portoviejo River a subject of rights and ordered remedial actions to address longstanding environmental degradation, marking a notable application of Ecuador’s constitutional Rights of Nature framework. On 9 January 2026, in response to a acción de protección filed in November 2025 by the Colectivo Intercomunitario por la Defensa Ecológica del Río Portoviejo (CIDER), the court found that the river’s rights had been violated by chronic contamination primarily from untreated sewage discharges from the Municipality of Santa Ana and deficiencies in wastewater treatment infrastructure, which had degraded water quality and ecosystem functions across the river basin. The plaintiff group, coordinated by José Castro Morteira, presented technical and scientific evidence documenting high levels of contaminants and ecological harm, and emphasized that the 100‑kilometer river supports water supplies for tens of thousands of residents and contributes to the Tumbes‑Chocó‑Magdalena biodiversity hotspot, making it an essential ecological and community resource.

In its decision, the court declared the Portoviejo River a rights‑bearing entity with special protection and ordered multiple measures: the development and execution of medium‑ and long‑term wastewater treatment plans led by the Municipality of Santa Ana; mechanisms for citizen and civil society participation in oversight; and the involvement of designated “guardian” entities including CIDER, the Defensoría del Pueblo, and local organizations to monitor compliance. The court’s ruling obligates local authorities to halt ongoing contamination and to implement concrete remediation actions, reflecting the constitutional recognition that nature has rights to exist, maintain its functionality, and be restored. Municipal authorities, represented by procurador síndico Víctor Narváez, indicated plans to appeal the decision to the Corte Provincial de Justicia de Manabí while also asserting that responsibility for water management is shared with other governmental bodies. The Portoviejo River became the fifth river in Ecuador recognized as a subject of rights, reinforcing jurisprudence that grants legal standing to ecosystems under Articles 71–74 of the Ecuadorian Constitution and expanding practical enforcement of rights of nature at the local judicial level.
